Description

Die Erfindung betrifft eine Wirbelsäulenstützvorrichtung, die es erlaubt, eine intersoma­ tische Arthrodese zu verwirklichen.The invention relates to a spinal support device that allows an intersoma table arthrodesis.

Bei einer Verletzung einer Zwischenwirbelscheibe ist es erforderlich, diese abzutragen und, um ihr Fehlen zu beheben, eine intersomatische Arthrodese zu realisieren, d. h. die Wirbelkörper zweier dieser Scheibe benachbarten Wirbel zu vereinigen, und dabei die durch die Abtragung entstandene Lücke zu schließen.If an intervertebral disc is injured, it must be removed and, to remedy their absence, perform an intersomatic arthrodesis, d. H. the Vertebral body to unite two vertebrae adjacent to this disc, and thereby to close the gap created by the removal.

Bei den heute verwendeten Techniken bestehen die häufigsten darin, entweder eine Platte, die durch äußere Verschraubung mit zwei Wirbelkörpern verbunden ist, oder eine zwischen den beiden Wirbelkörpern angeordnete Wirbelzwischenplatte aus porösem Po­ lyäthylen zu verwenden. In beiden Fällen wird ein Transplantat oder ein Knochensubsti­ tut zwischen den beiden Wirbelkörpern eingeschoben, um ihre Verbindung zu verwirkli­ chen.With the techniques used today, the most common are either one Plate that is connected to two vertebral bodies by external screwing, or one intermediate porous butt plate between the two vertebral bodies to use polyethylene. In both cases, a graft or a bone substitute inserted between the two vertebral bodies to confuse their connection chen.

Die verwendeten Vorrichtungen weisen jedoch Nachteile auf, wobei der Hauptnachteil der der Verwendung von Schrauben ist, die dazu neigen, sich zu lösen.However, the devices used have disadvantages, the main disadvantage is the use of screws that tend to loosen.

Diesen Nachteil haben alle Prothesen gemeinsam, aber er kann äußerst schwerwiegende Folgen haben, wenn es sich um einen empfindlichen Bereich, wie es Wirbelsäule ist, han­ delt. All prostheses have this disadvantage in common, but it can be extremely serious Consequences if it is a sensitive area, such as the spine delt.  

Außerdem kann die Verwendung von Polyäthylen insbesondere aufgrund von Teilchen, die dazu neigen, sich von der Platte zu lösen, pathologische Folgen haben.In addition, the use of polyethylene, in particular due to particles, that tend to detach from the plate have pathological consequences.

Fig. 4 eine perspektivische Darstellung einer zweiten Ausführungsform der erfin­ dungsgemäßen Vorrichtung. Fig. 4 is a perspective view of a second embodiment of the inventive device.

Bezugnehmend auf Fig. 1, 2 und 3 kann man sehen, daß eine erfindungsgemäße Wirbel­ säulenstützvorrichtung eine flache und langgestreckte Platte 1 aufweist, deren Mittelbe­ reich 2 größer als die sich verjüngenden Endbereiche 3 und 4 ist und die so gebogen ist, daß sie einen offenen flachen Ring bildet.Referring to Fig. 1, 2 and 3 it can be seen that a vortex invention columnar support device has a flat and elongate plate 1 whose Mitt same is rich 2 greater than the tapered end portions 3 and 4 and which is bent to an open forms a flat ring.

Die Kanten der Endbereiche 3 und 4 sind gezahnt, sie haben zum Mittelbereich 2 gerich­ tete Zähne 30 und 40, so daß die Endbereiche 3 und 4 die Form von Greifern haben. The edges of the end regions 3 and 4 are toothed, they have teeth 30 and 40 directed towards the central region 2 , so that the end regions 3 and 4 have the shape of grippers.

Der Mittelbereich 2 weist eine mit einem Innengewinde versehene Bohrung 20 auf, die ein Anpassen eines nicht gezeigten Einbaugeräts, das im wesentlichen aus einem Schaft besteht, der an einem Ende ein Außengewinde aufweist, erlaubt.The central region 2 has a bore 20 which is provided with an internal thread and which allows an installation device (not shown), which essentially consists of a shaft and has an external thread at one end, to be adapted.

Das Anbringen einer erfindungsgemäßen Wirbelsäulenstützvorrichtung wird auf folgende Weise durchgeführt: Nach der Abtragung der Zwischenwirbelscheibe und der sie begren­ zenden Knorpelplatten werden die Wirbelkörper auseinandergespreizt, und die ein Kno­ chenimplantat beinhaltende Stütze wird zwischen den Körpern eingefügt. Vorher werden die Endbereiche 3 und 4 der Stütze, deren Höhe in Abhängigkeit von dem auszuglei­ chenden Zwischenraum zwischen den Wirbeln gewählt wird, je nach der Größe der Wir­ belkörper mehr oder weniger aufgespreizt. Nach Lockerung des auf die Wirbel ausgeüb­ ten Drucks kommen die Zähen 30 und 40 in Eingriff mit der Kortikale der Wirbelkörper, wobei ihre Greiferform das Verschieben der Stütze verhindert.The attachment of a spine support device according to the invention is carried out in the following manner: after the removal of the intervertebral disc and the cartilage plates limiting it, the vertebral bodies are spread apart, and the support including a bone implant is inserted between the bodies. Before the end areas 3 and 4 of the support, the height of which is chosen depending on the gap between the vertebrae to be compensated, depending on the size of the vertebral body more or less spread. After releasing the pressure exerted on the vertebrae, the teeth 30 and 40 come into engagement with the cortical of the vertebral bodies, their gripper shape preventing the support from shifting.

Das Baukastenprinzip der Größe der Stützen erlaubt es aufgrund der Möglichkeit, die Endbereiche 3 und 4 aufzuspreizen oder zusammenzubringen, die Anzahl der bei einem Eingriff erforderlichen Stützen zu begrenzen, wobei die Stützen nur in der Höhe variie­ ren.The modular principle of the size of the supports allows, due to the possibility of spreading or bringing the end regions 3 and 4 together, to limit the number of supports required during an intervention, the supports only varying in height.

Bezugnehmend auf Fig. 4 kann man nun sehen, daß die erfindungsgemäße Wirbelsäu­ lenstütze bei einer zweiten Ausführungsform zu beiden Seiten des Mittelbereichs 2 zwei scharfe und gezahnte Spitzen 5 und 6 aufweist, die im rechten Winkel zu der Seite der Endbereiche 3 und 4 gebogen sind.Referring now to Fig. 4, it can be seen that the spine according to the invention, in a second embodiment, has two sharp and toothed tips 5 and 6 on either side of the central region 2 which are bent at right angles to the side of the end regions 3 and 4 .

Die Spitzen 5 und 6 sind dazu bestimmt, unter Krafteinwirkung in die Wirbelkörper hin­ eingedrückt zu werden, die vorher mit Hilfe einer Bohrschablone eingestochen wurden, was das Fixieren des adäquaten Abstands zwischen den Wirbelkörpern erlaubt.The tips 5 and 6 are intended to be forcefully pressed into the vertebral bodies, which were previously inserted with the aid of a drilling template, which allows the adequate distance between the vertebral bodies to be fixed.

Die Spitzen 5 und 6 vervollständigen die Fixierung der Stütze und ermöglichen insbe­ sondere ein Beibehalten des Abstands der Wirbelkörper.The tips 5 and 6 complete the fixation of the support and in particular make it possible to maintain the distance between the vertebral bodies.

Es ist anzumerken, daß die Spitzen aus federelastischem Metall derart hergestellt werden können, daß sich bei Körpertemperatur ein leichtes Zusammenziehen einstellt. It should be noted that the tips are made of resilient metal in this way can cause a slight contraction at body temperature.  

Gemäß einer anderen nicht gezeigten Ausführungsform kann die Stütze zwei an der ei­ nen und anderen Seite des Mittelbereichs angeordnete Befestigungsklammern aufweisen, die an ihrem Ende jeweils eine Öffnung aufweisen, die das Durchführen selbsthemmender Schrauben erlaubt, die, wenn sie einmal mit den Öffnungen in Eingriff stehen, nicht mehr herausgezogen werden können.According to another embodiment, not shown, the support two on the egg NEN and other side of the central region arranged fastening clips which each have an opening at their end, which makes the passage more self-locking Screws allowed, which once they are in engagement with the openings, no longer can be pulled out.
